The Wyoming Mailing Address Change Form (PDF) is a document used to update mailing addresses with the Wyoming Secretary of State's office. It can be used to change the address of a business, organization, or individual who is registered to do business in the state of Wyoming. This form includes two types: the Business Address Change Form and the Individual Address Change Form. The Business Address Change Form requires the name of the business, the business address, and the name and signature of an authorized representative. The Individual Address Change Form requires the name of the individual, the new address, and the individual's signature. Both forms must be signed and notarized before filing.
